摘要

Mice were treated with mitomycin C, cyclophosphamide, amuscarine, colchicine, or vinblastine sulfate, and meiotic prophase cells analyzed for synaptonemal complex damage. All test agents caused synaptonemal complex breakage and synapsis irregularities, although propensities for inducing specific types of damage at S-phase or prophase stages varied among the chemicals. The data indicate that SC analysis can reveal chemical-specific alterations to meiotic homologue pairing/synapsis which have not generally been recognized, and which theoretically may be implicated in nondisjunction.
